Voting Question: compare which is really a bad choice?

i see lots of demos bad mouthing cindy McCain because she had a problem with prescription addiction of pain meds after a injury.but they never mention obamas choice to do a illegal drug called cocaine .odd there is a difference one was hurt and got hooked do to a physical injury ,one just decides to do a illegal drug for fun.its all about judgement isnt it.personally i could care less she isnt running for office he is.thats the only differance but im sure he only did it one time.
